The paper presents the research results of the efficiency study of biological
products in corn growing technologies on different fertilization background and
main soil tillage practices. The positive effect of microbial preparations on crop
yields and output quality was established.
Keywords: microbial drugs, plant growth regulator, fertilization
background, tillage, corn.
The solution to the food supply problem and welfare improvement of
Ukraine is largely dependent on the development of agriculture and its efficiency
increase. The basis for high yields formation, in addition to the genetic potential of
the plants is the technology of their cultivation.
Corn – one of the most valuable crops. Its outputs are used in animal
husbandry, food and processing industries. In some countries, about 20–35% of
the gross corn harvest is used for food needs, 15–20 % – for technical, and 50–65
% for livestock feeding [1, 2]. Growing demand for corn on both domestic and
foreign markets necessitates the yield increase of this universal culture.
The research results conducted for several years in different soil-climatic
zones of Ukraine and abroad, testify the positive impact of deep main tillage on the
growth, development and productivity of corn [3]. Fertilization – is one of the
effective technological measures used for improvement of corn productivity. Corn
versus other grains responds better to fertilization and due to the long growing
season uptakes nutrients from the soil almost till the end of grain ripening [4].
Pre-sowing seeds bacteryzation along with the use of fertilizers in corn
growing is one of the promising agricultural means. Use of microbial preparations
in agriculture promotes not only increase in plant productivity but also in grain
quality, and also creates a high concentration of useful forms of microorganisms in
the root zone of plants, which in turn positively affects the passage of specific
biological processes in soil [5]. Pre-sowing seeds bacterization sometimes is quite
difficult to combine with other agricultural means – like pesticides treatment to
protect seeds from pathogens. Nowadays there is an industrial (factory) technology
of simultaneous seeds bacteryzation with protectants, which solves this problem
[6].
Efficient and rational use of fertilizers, optimization of plants nutrition
through the use of modern biological preparations is one of the priority means that
can provide a guaranteed and competitive production of corn. Thus, the efficiency
study of the microbial preparations at cultivation corn at different fertilization and
tillage is relevant and is of a practical importance.
Materials and methods. The study of the combined effect of biological
preparations at pre-sowing seeds bacteryzation combined with foliar treatment of
crops with growth regulator on different backgrounds of mineral fertilizer and
basic soil tillage methods on the corn productivity in the Northern Steppe of
Ukraine were conducted in field experiments by three factor scheme for the period
2011–2013 (Table 1).
Experiments were conducted using two primary tillage means – plowing to a
depth of 25–27 cm and disking on the depth of 12–14 cm. The following fertilizer
systems were used: 1 – without fertilizers; 2 – N20P20K20; 3 – N40P40K40. In each
system there were variants without the use of biological preparations and with
seeds inoculation using microbial preparation Agrobacteryn, 60 ml per hectare
norm of seeds and Biogran, both separately and in combination with a growth
regulator Biolan (20 ml/ha). Foliar application of growth regulator was performed
at phase of 6-8 corn leaves. Corn hybrid used in the experiments Lyubava 279 MV.
Pre-crop – soybeans. The growing technology - common for the area, except
for the studied factors. Experiments establishment, observation, recording and
sampling was carried out in accordance to the methods of field experiment by
Dospehov [7].
Seed inoculation was carried out at the same day with planting using
conventional methods for bacterial preparations use and manufacturers
recommendations [8].
The experiments were performed on plain black heavy clay loam soils.
According to the research center “Oblderzhrodyuchyst” the plow layer contains on
average 4.69% of humus, easily hydrolyzed nitrogen – 13.7, mobile phosphorus –
10.0 and exchangeable potassium – 15.1 mg/100 g of soil.
Hydrothermal coefficient (HTC) is used to describe corn provision with
moisture and heat during certain periods of plant growth and development and for
the whole growing season. In 2011 the average HTC figure during vegetative
period of corn was 0.75 while the average long-term index is 1.05. However, it
should be noted that in the critical period of growth and development of corn HTC
was 2.3 at a norm of 1.18, which made it possible to obtain a relatively high yields
of corn. During the 2012 growing season the HTC was 0.48. In April, it was
below the long-term index up to 70.4%. In May - by 65.3%, in June – by 62.7%,
in July – by 50.9%, in August and September – 48.7% and 81,4%, respectively. At
a critical period of corn growth and development (second-third decade of June)
hydrothermal coefficient was within the 0.03 to 0.19 range, which had indicated
the significant shortage of rainfall and severe drought. Such weather conditions
had affected the final crop productivity. In 2013 the HTC in April was 0.5 at a
norm of 1.35. In May and June the HTC values were close to the average indices.
July and August were characterized with higher (2.8 and 3.3 °C, respectively)
average air temperature as compared to the long-term average and lack of effective
precipitation. HTC during this period was respectively 0.4 and 0.3, at long-term
average – 1.16 and 0.80. Optimal soil moisture level during the critical period of
corn development had ensured the formation of high yields.
Results and discussion. Comprehensive analysis of the growing conditions
of corn under the use of microbial preparations, both separately and in combination
with plant growth regulators, in different ways and on different fertilizer
background and different main soil tillage techniques had showed the significant
dependence of corn yield from the investigated factors and environmental
conditions.
Under the sufficient moisture conditions in 2011 a relatively high corn yield
was formed in variants with both tillage means. Thus, plowing either on the
background without fertilizers or at application of 20 kg/ha of active ingredient had
a higher grain yield in the variants with pre-sowing seeds inoculation with
phosphorous mobilizing preparation Agrobacteryn – 11.99 and 12.12 t/ha that is
respectively 1.42 and 1.55 t/ha or 13.4 and 14.7% increment over the control
(without fertilizers and without inoculation). In variants with the highest fertilizers
background the highest values were obtained in variants with seeds bacteryzation
with microbial preparation of complex action Biogran followed by foliar
application with Biolan. That which gave extra 2.22 t/ha or 21.0%, compared to the
absolute control and 1.27 t/ha or 11.0% - to the variant without seed treatment in
same experimental block (Table 1).
At minimal tillage technology (disking to a depth of 12–14 cm) at natural
background and at application of N20P20K20 the Biogran preparation was shown to
be most efficient. That allows to receive respectively, 1.02 and 2.25 t/ha compared
to the absolute control. Both at plowing and disking on the N40P40K40 background
the highest yields were obtained in the variant with combined application of
Biogran with Biolan – 10.47 t/ha at 8.17 t/ha level in absolute control.
In dry conditions in 2012 for plowing at all studied fertilizers backgrounds,
the significantly high increase of corn yield comparing to the absolute control
(without fertilizer and without seed treatment) was formed in variants with seeds
bacteryzation with microbial preparation Biogran – 0.55 t/ha (14.2%) – on natural
background; 0.81 t/ha (21.0%) – at 20 kg/ha of fertilizer; 0.52 t/ha (13.5%) – at
N40P40K40 background.
The maximum yield under disking on the background without fertilizers and
application of N20P20K20 was received in variants with seeds treatment with
Biogran – 3.45 and 3.58 t/ha, respectively, which gave the opportunity to get extra
0.55 and 0.68 t/ha of grain compared to the control. Pre-sowing seeds
bacteryzation with microbial preparation Agrobacteryn wasshown to be the most
efficient on the highest fertilizers background – N40P40K40.
In the agro-climatic conditions for that year in variants with complex use of
microbial preparations for seed treatment and foliar treatment of crops during the
growing season with growth regulator Biolan the yield shortfall was observed – on
both tillage systems and fertilizer backgrounds, compared to plots with pre-sowing
seeds inoculation. On average, this index within the experiment had ranged 0.01 –
0.86 t/ha.

In 2013 at plowing to a depth of 25–27 cm the significantly higher corn
yield was formed in variants with seeds treatment with microbial preparation of
complex action Biogran on all fertilizers backgrounds. Thus, on the background
without fertilizers and application of N20P20K20 at seed inoculation it was,
respectively, 8.41 and 8.45 t/ha. For N40P40K40, in combination with foliar
treatment of crops with growth regulator Biolan the yield was 8,07 t/ha. This gave
the opportunity to receive an extra 0.86; 0.92 and 0.54 t/ha or 11.8; 12.2 and 7.2%
of grain respectively, compared to the control without fertilizer and without seed
treatment.
In variants with disking higher yields were obtained under the use of
microbial preparation of complex action Biohran. On the background without
fertilizers the maximum yield of corn grain was formed in variants with seeds
inoculation and foliar treatment with Biolan – 7.78 t/ha, which was 0.61 t/ha higher
compared to the control without inoculation. Use of Biogran at N20P20K20 and
N40P40K40 fertilizers backgrounds for pre-sowing seeds treatment had ensured
receipt of additional yield compared to the control without fertilization and
inoculation – 0.63 t/ha (8.5%) and 0.81 t/ha (11.3%), respectively.
The research data have shown that the average corn yield increase for 2011–
2013 ensured by the use of biological preparations was 0.47 – 0.58 t/ha (6.2 –
7.6%) n variants with plowing and 0.38 – 0.73 t/ha (6.0 – 11.5%) – in variants with
disking. The average data over the experiment had indicated that deeper tillage
(plowing to a depth of 25-27 cm) compared to the shallow (12-14 cm disking) had
ensured corn yield increase from 6.77 to 8.02 t/ha. Application of fertilizers in
variants with plowing had provided the yield increase of 7.90 t/ha in the plots
where studies were conducted on a natural background and 8.15 t/ha on a
N20P20K20 background. Higher mineral fertilizers doses (40 kg/ha of active
ingredient) had resulted in yield decrease – 8.01 t/ha. For variants with shallow
tillage corn yield under the different fertilizing systems had increased from 6.57
t/ha on a natural background, respectively, to 6.66 and 7.08 t/ha at application of
mineral fertilizers at doses 20 and 40 kg/ha of active ingredient.
It should be noted that biological preparations had the maximum impact on
the formation of biological productivity of corn in experiment conducted in 2012
characterized with the drought conditions. Corn yield through the use of biological
preparations in 2012 had increased from 9.0 to 15.6%. In 2011 these figures was
4.8 – 9.0%, in 2013 – 4.4 – 6.6%.
The results of starch content in corn had indicated the higher values for this
figure in variants with plowing on natural background under the seeds treatment
with Agrobacteryn – 66.93%, which was 2.34% higher comparing to control
without inoculation. In other variants yield the decrease of this quality indicator on
0.04–4.52% was observed (Fig. 1).

Fig. 1. Influence of studied factors on the starch content in corn seed, average for
2011–2013, %
Application of mineral fertilizers with main tillage in doses N20P20K20 and
N40P40K40 in control variant (without inoculation) the gradual decrease in starch
content in seeds was observed – 1.10 and 2.98 %, respectively. However, the use
of biological products in the blocks with mineral fertilizers the starch content as
compared to the control values had increased. Using 20 and 40 kg/ha of active
ingredient the highest values in the variant with Biogran. The starch content was
higher compared to control, respectively, by 1.00 and 2.35%. Application of
biological products had not contributed to the increase of starch content in corn at
corn growing at shallow soil tillage.
Estimation of economic efficiency of corn growing confirm the general
pattern: the use of microbial preparations was more effective on the background
without fertilizers, while at higher fertilizer doses the profitability level had
decreased. Due to the yield differences depending on the studied technological
means and variability of production costs the profitability had also changed. The
best values of relatively net profit and higher profitability indicators were obtained
in variants with plowing. Disking had resulted in lower values of studied these
indices. Thus, relatively net profit form the use of biological preparations on

various fertilizers background under the deep tillage had ranged from 5 137 to
7 120 USD/ha at profitability level 109.8–196.8 %, hallow tillage had respectively,
4 261–5 560 UAH/ha and 91.0–172.9%.
The use of microbial preparations was shown to be a promising agricultural
practice and efficiency reserve for corn growing in arid regions of Northern Steppe
Ukraine. It ensures high grain yields at favorable weather conditions at deep tillage
(plowing to a depth of 25–27 cm), and shallow tillage (disking on depth of 12-14
cm). At crops growing on natural background at both studied tillage methods for
better effect it is recommended to use pre-sowing seeds inoculation with microbial
preparation of complex action Biogran, that in average for 2011–2013 had ensured
extra 0.94 t/ha (12.8 %) of grain in plots with plowing and 0.67 t/ha (11.0%) – in
plots with disking. At corn growing using moderate doses of mineral fertilizers (20
kg/ha active ingredient) using plowing it is recommended to use Agrobacteryn for
seeds bacterization, while at disking it is recommended to use Biogran. Both
preparations ensure yield increase by 13.7 and 19.6 %, respectively.
